Rated 5.0 out of 5.0 by Orkie Does What it is supposed to!
City installed new water meters with a check valve in the system. Old system did not have check valve. Since the new water meter was put in my water heater started to relieve thermal caused pressure through the safety valve. Always water in the bucket as our basement has no drains.
Our city water pressure was 70 PSI. Matched the tank pressure to this, installed the tank, and the water heater safety valve has not released any water due to pressure.
Good value and easy to install.

Rated 5.0 out of 5.0 by Toby422 Easy install and directions are great!
The thermal expansion tank was very easy to install as were the directions to follow. The thermal expansion tank was a replacement for a unit which was worn out. The tank was a near identical replacement for the exixting unit. I would highly recommend this product if you have a hot water heater that has a back flow preventor installed somewhere in line to allow the water to expand. Othewise you may create a situtation where the pipes may burst due to over pressure.

After installing a solar hot water system that utilizes a 120 gallon tank, I started having elevated water pressure (at times) in the house. I was also getting pipe "hammering," and was afraid I'd end up with a broken pipe. My previous hot water heater was a 50 gallon unit which must have had the same issues, but to a much lesser extent. I never noticed the problem until the larger tank was installed.
The Amtrol thermal expansion tank seems to have solved the problems. It's been in for about two weeks now, and haven't had a single high pressure episode, or any pipe hammering since. The unit appears to be of very high quality, and I had no problems installing it...very simple.
I ended up making my own mounting bracket for the unit. There are commercially available brackets made, but the Home Depot did not carry them, or offer them on their website. To save the cost + shipping from the other suppliers, I built a simple unit out of plywood, and a couple of large hose clamps.

Rated 5.0 out of 5.0 by Jeff Great product! Replaced 8 yr old original
This item came with my house upon its construction. That was 8 years ago. Recently, it started leaking down the side (corroded around seam). It was time to buy a new one. Looked no further than here at Home Depot, purchased same item, great price, fast shipping. If needed, will buy again in the future.
